To aZZ whom it may concern Be it known that I, JOSEPH A. MOLLITOR, a;citizen of the United States, residing at Chicago, in the county of Cookand State of Illinois, have invented certain new and useful Improvementsin CushionTires, of

which the following is a specification.

This invention relatesto cushion tiresof that class which arecharacterized byan inclosed core, the invention being directedmore'particularly to the core, and having for its object to provideacore of novel form which is readily removable in order-that it may be,renewedwhen necessary.

The invention also has for its ob ect to provide a novel and improvedmeans'for' securing the core within the tire.

With these objects in view, the invention consists inacombination andarrangement of parts to be hereinafter described and claimed, referencebeing had to the accompanying drawing in which a cross-section of thetire and the inclosed core is shown.

Referring specifically to the'drawing, 5

denotes the'outer casing of the tire, the same having the usual 'clencher beads 6 at itsbase. The ends of the casing forming thebase arespaced apart so that a space or o enlng 7 is produced which extendsentirely t irough the base and communicates with the interior of thecasing. p

The casing 5 'incloses a cruciform core 9 having lateral and oppositelyextending wings 10, the extremities of which are flared or dovetailed,as indicated at 11, and seat in correspondingly shaped diametricallyopposite grooves 12 in the side walls of the casing, on the insidethereof. The core also has top and bottom wings l3 and l t,respectively. The top wing 13 has a slight outward taper and extends inthe direction of the tread.

portion of the casing, and'is adapted to come 1n contact with the casinwall at this point,

top wing has a depression 15 which coincides with a head 16 formed onthe inside of the casing wall. The bottom wing 14: extends toward thebase of the tire, and has a reduced portion 17 which fits in the space7.;

The surface of the core 9 has a reinforcement 18, and the interiorsurface of the casing 5 also has a reinforcement 19, in order to reducethe wear between the contiguous portions of the casing and the core. The

casing also has an embedded reinforcement 20 located in its base portionand extending along the sides of the casing, and also across 'having itsends forming the base of the tire spaced apart, and a cruciform coreincloscd in the casing, said core being separate from the casing andhaving an integral wing extending into the space between the ends of thecasing at the base thereof.

In testimony whereof I affix my signature in presence of two witnesses.
